Abstract:
Objective To investigate the hygienic quality of drinking water in rural areas of Xiamen and to provide scientific bases for the improvement of drinking water quality and protection of human health.Methods The well water samples were sampled randomly according to the proportion and the water quality was analysed and the incidences of water-borne diseases were investigated in Xiamen rural areas.Results Water sources for drinking water in most parts of Xiamen rural areas are shallow-layer ground-water.As being polluted by surface ranoff water,the indices of total bacte-rial count and coliform bacteria in the well water were heavily over the standard with the over standard rates61.6%and85.1%respectively.The contents of fluoride in drinking water were at the higher levels(the highest one was1.6mg /L)in some villages and still there were more villages where the iodine contents in drinking water was at the lower level.The iodine content in well water,spring water and tap water was11.1,2.5and4.45?g /L respectively,in which the unqualified rate was48.3%,90%and58.1%respectively.The incidence of dental fluorosis in school-age children was70%in the high fluoride areas and the incidence of endemic goiter was20.9%in the low iodine areas.Conclu-sion The main hygienic problem of drinking water in rural areas of Xiamen was biological pollution and lower iodine contents and higher fluoride contents in water in some areas.In order to eliminate the water-borne diseases,the most important rural sanitary measures need to be taken:improving the sanitary conditions around the wells,repairing the well wall s and using deep ground-water or drinking water and developing centralized water supply in the areas with unbal-anced health-related microelemeuts in drinking water if possible in some villages.
